SHUTTLE FOR SIDE-MOTION-FEELER LOOMS.

Specification of Letters Patent.

Patented June 22, 1920.

Application filed February 21, 1920. Serial No. 360,320.

concern:

Be it known that I, EDWARD S. STIMISON, acitizen of the United States, and resident of I-Iopedale, county of Worcester, Stateof Massachusetts, have invented an Improvement in Shuttles for Side-Motion-Feeler Looms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to improvements in shuttles for use in side motion feeler looms. In such types of looms, as is well known to those skilled in the art, a feeler is employed which, upon the beat-up of the lay, enters through a feeler slot in the wall of the shuttle and contacts with the mass of filling upon the filling carrier. The feeler mechanism is so constructed that when the running filling has reached a predetermined degree of exhaustion, or has become entirely exhausted, the feeler has a side motion some portion of it, slipping upon the smooth surface of the filling carrier, and this side motion is utilized to effect the initiation of filling replenishment or other change in the operation of the loom.

In the operation of looms the shuttle is sometimes mispositioned by reason of slight rebounding from the picker stick, or because of its failure fully to enter the shuttle box at the feeling end of the loom and resulting in either case in bringing the path of the feeler nearer the butt end of the shuttle than the normal path of the feeler. This brings the feeler opposite the smooth outer wall of the shuttle; or opposite one of the jaws which clamps the butt of the filling carrier in the shuttle. In such case the feeler engages either the smooth wall of the shuttle or the smooth surface of the shuttle jaw and a side motion takes place in the same manner as if it had engaged the smooth surface of a depleted filling carrier.

Patent No. 1,302,689, granted May 6, 1919. to T. F. Brazil, discloses, in broader claims. means for preventing premature action of a side motion of the feeler when the latter engages a misplaced shuttle. Its specific mechanism disclosed therein comprises serrations upon the outer wall of the shuttle jaw which is exposed by the feeler slot which extends shuttle.

Patent through one of the walls of the No. 1,303,583, granted May" 13,

1919, to Osgood, discloses a shuttle in which the feeler slot does not extend along the shuttle aws, but in which a series of vertical serrations are provided in the outer I wall of the shuttle immediately beyond the end of the feeler slot and opposite the shuttle jaws, theseserrations being adapted to engage the feeler and prevent premature op eration thereof when the shuttle is longitudinally misplaced in the shuttle box.

The present invention contemplates the provision of a simple means by which a usual form of shuttle may be provided with means for preventing premature action of a side motion feeler when the shuttle is misplaced without the necessity of a special construction either of the shuttle body or of the shuttle jaws. This is accomplished by providing means within the feeler slot, located outside of the normal field of operation of the feeler, which are adapted to engage the feeler if the shuttle is misplaced longitudinally, and prevent improper actuation thereof, said means being so constructed as to be readily applied to a usual type of shuttle.

A further object of the invention is to provide the shuttle with means for preventing improper operation of the side motion feeler which can be readily assembled in usual types of shuttles and which can be readily removed and replaced.

Other objects and features of the invention will more fully appear from the following description and the accompanying drawings and will be pointed out in the annexed claims.

In the drawings, which'represent a pre ferred embodiment of the invention,

Fi re 1 is a side elevation of the end of the shuttle having my invention embodied therein.

Fig. 2 is a plan view of the end portion of the shuttle showing the shuttle jaws clamping a filling carrier therein and illustrating the means for preventing improper operation of the side motion feeler.

It will be obvious from the statements heretofore made that the construction and operation of the loom and ofthe side mo tion feeler mechanism is unafiected by the present invention which has only to do with the construction of the shuttle itself. Consequently the to the shuttle.

be of any usual type. As illustrated herein the body 1 of the shuttle is provided with the usual longitudinal recess 2 extending through the shuttle from top to bottom to receive the filling carrier 3 which, as indicated in dotted lines, may be a wooden bobbin of the usual type having an enlarged base provided with rings 4 which are grasped between the shuttle jaws 5 and 6. The front wall 7 of the shuttle is provided with a longitudinal feeler slot 8 the walls of which are in parallelism with the bottom and top of the shuttle. The slot 8, in usual shuttle construction, extends toward the end of the shuttle beyond the jaw 6.

In the normal operation of the loom the f'eeler is inserted during the beat-up of the lay through the feeler slot opposite to the smooth barrel of the filling carrier and if it encounters a mass of filling upon said filling carrier is prevented from si'dewise movement. When, however, the filling is depleted, the feeler engages the smooth surface of the barrel of the filling carrier and slips longitudinally thereon, thereby effecting an initiation of mechanism which produces a changein the operation of the loom. If the shuttle becomes improperly placed at the time the feeling action occurs, the feeler is likely to engage the outer smooth face of the shuttle jaw 6 in which case the feel'er will slip side-wise and effect a change in the operation of the loom just as if it had engaged the smooth barrel of the filling carrier.

The present invention consists in introducing into the feeler slot means which will prevent the side-wise movement of the feeler, the means thus introduced being of such a character that it will not wear rapidly and preferably being so secured as to be readily removed and replaced A most simple expedient, which is illustrated'in the drawing, comprises a pin, preferably a plurality of pins 9' and 10 spaced apart a considerable distance, which are inserted vertically through the wall 7 of the shuttle across the feeler slot 8 outside or beyond the normal field of operation of the feeler.

As shown herein the pins 9 and 10 are both located opposite the aw 6 of the shuttle and serve to engage the feeler if the shuttle is sufficiently misplaced to place the pins 9 or 10 in the path thereof. Any number of pins land 10 may be employed and spaced apart any desired distance as required by the particular kind of shuttle which is employed.

The pins 9 andlO desirably are of sufiicient'ly small diameter to enter into the recess or serrations in the end of the feeler and thereby lock it against side-wise move ment during the beat-up of the lay. As illustrated herein these pins are shown asdriv'en vertically downward through the wall 7 of the shuttle transversely across the 'feeler slot 8. Thus they are easily applied to any usual type of shuttle and are capable of being readily removed and replaced when worn or broken. The presence of these pins in the wall of the shuttle will not interfere 7c with the use of the shuttle in looms having other types of feelers or in non-automatic looms. The shuttles, therefore, may be equipped with this invention without danger of interference with other uses of the shuttles than in the side motion feeler auto-. matic filling replenishing loom. The embodiment of my invention in usual shuttles may also be made without anyniaterial ex: pense and without the necessity either of special construction of the shuttle body or of the shuttle jaws. In fact, my invention can be incorporated into an ordinary shuttle Without difiiculty thereby providing a ready supply of shuttles for a side motion feeler loom which will readily and effectively insure the proper operation of the feeler mech anism notwithstanding the misplacement of the shuttle.

It will be understood that various modifications in form, construction and arrangement of parts may be made within the spirit and scope of the following claims.

aving thus described my invention, what claim as new and desire to secure by Letters Patent, is:

l. A shuttle for use in side motion 'feeler looms provided with a filling carrier recess and means to clamp and hold the filling carrier therein, one wall of said shuttle having a feeler slot to permit the passage of the feeler therethrough, means located within said feeler slot out of the normal field of operation of the feeler adapted to engage the feelerQif the shuttle is longitudinally misplaced at the time of feeling andprevent premature actuation of said feeler.

2. A shuttle for use in side motion feeler looms provided with a filling carrier recess and means to clamp and hold the filling carrier therein, one wall of said shuttle having a feeler slot to permit the passage of the feeler therethrough, a metallic member fixedly secured within the feeler slot in said shuttle wall outside of the normal field of 1-15 operation of the feeler adapted to engage the feeler, if the shuttle is longitudinally misplaced at the time of feeling and prevent side motion of saidfeeler.
